Verification Images

  • Experimental Validation Results for SIRP alpha Antibody (YA9785)
    Western blot analysis was performed on protein extracts (25 μg) from A549 (lane 2), 293T (lane 3), THP-1 (lane 4), and U87 (lane 5) using SIRP alpha antibody. Proteins were transferred onto a 0.45 μm PVDF membrane using the Trans-Blot® Turbo™ system for 13 min. The membrane was then blocked with 5% nonfat milk in TBST (HY-K1025) for 1 h at room temperature. The primary antibody (1:1000) and loading control antibody GAPDH Antibody (HRP) (HY-P80954A) (1:5000) were diluted in 5% nonfat milk in TBST and incubated with the membrane overnight at 4°C. After washing, the membrane of primary antibody was incubated with HRP-conjugated goat anti-rabbit/mouse IgG secondary antibody (HY-P8001/HY-P8004) (1:5000) diluted in 5% nonfat milk in TBST for 1 h at room temperature. Protein bands were visualized using an Ultra High Sensitivity ECL detection kit (HY-K1005).

Background

  • Function

    SIRP alpha is an Immunoglobulin-like cell surface receptor for CD47. Acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. Supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. May play a key role in intracellular signaling during synaptogenesis and in synaptic function (By similarity). Involved in the negative regulation of receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors or insulin. Mediates negative regulation of phagocytosis, mast cell activation and dendritic cell activation. CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. Plays a role in antiviral immunity and limits new world arenavirus infection by decreasing virus internalization (By similarity). Receptor for THBS1. Interaction with THBS1 stimulates phosphorylation of SIRPA (By similarity). In response to THBS1, involved in ROS signaling in non-phagocytic cells, stimulating NADPH oxidase-derived ROS production[1].
